iNetCalc is an internet connection speed meter destined for keeping
record of your Internet costs while using Wi-Fi, xDSL, VPN, GPRS and
dialup connections, when every byte passed the connection has to be
recorded. Connection time is also taken into account.

All necessary connection information is conveniently presented:
your internet connection online speed, incoming and outgoing channels loading, average internet connection
speed, sent and received traffic, bandwidth monitor, connection time,
money spent (with tariff settings enabled). There are both global
statistics for the chosen connections and a separate one for each
connection for the current day and month.
